Title: Pressure fixing device
Inventor: KADOI HARUO
IPC: G03G15/20
Filed: 1987-12-08
Abstract: PURPOSE:To suppress the increase of torque at the time of feeding and ejecting copy paper at minimum by providing an oscillation generator in which an image can be fixed by supplying micro oscillation of high frequency on either a fixing roller of a backup roller. CONSTITUTION:A micro oscillation generator 7 consisting of an ultrasonic oscillator or an electromagnetic oscillator is provided in the center of an arm 6 in a pressure fixing device. And by supplying the micro oscillation of high frequency on the fixing roller 1 brought into contact with the plane of the image, a toner image formed on the surface of the copy paper 3 is fixed by impact pressure. Therefore, it is desirable to form the fixing roller 1 smaller in diameter and weight than that of the backup roller 2. Also, since fixing is performed by the impact pressure of the fixing roller 1, it is not required to always add high pressure between the rollers 1 and 2 differently from an on-going pressure fixing device. Also, by providing a cavity (t) between the fixing roller 1 and the backup roller 2 in a state where no paper is fed, it is possible to suppress impact torque being added on a motor 11 at the time of feeding the copy paper 3 at the minimum level.

Title: Door open/close detecting system
Inventor: NOGUCHI AKIO
IPC: G05B9/02
Filed: 1987-12-11
Abstract: PURPOSE:To transmit the door open/close state without adding newly a door open/close detecting element, a signal line, etc., by applying a 2nd object signal to an existing input/output signal line in response to the door open/close actions. CONSTITUTION:An existing switch SW1 is used for ON/OFF actions of a DC power supply 1 against the door open/close actions for safety of products. Then an output control signal, i.e., a remote control signal (b) is used as an input signal as conventional so that the door open/close state can be recognized. For a concrete action, a control circuit IC2 contains an A/D converter serving as an input port and sets the slice level at 2V. The voltage of a high level ViH which is applied to the A/D input port is set at about 4.6V since the sum of the current obtained from Vi=24V and the current obtained from V2=20V serves as the electromotive force. Then the voltage ViH is binarized at the slice level 2V, recognizes the door open/close state, and controls the output of a control signal C of a necessary drive circuit, etc.
